EDEMO Armaspec AR9 Gen4 Stealth Recoil Spring Stainless/Black EDEMO3 Used Condition Fair. The SRS is designed to keep the buffer spring from rubbing against the inner wall of the buffer tube providing smooth quiet operation and the second stage helps reduce the felt recoil significantly. NOTE: The new GEN4 version does not have the o-ring on the weight. To eliminate any potential failure points we changed the screw to a roll pin across the plastic end piece and the cap is machined on the rodm replaced the snap ring with a washer. 9mm Bolt Carriers ONLY: For proper function of the SRS-9 in your 9mm rifle or pistol the extra weight on the back of the bolt carrier needs to be removed. It is held in with a spring pin.
